yo lo hice de la siguiente manera try { Scanner in = new Scanner(System.in); int n = in.nextInt(); in.close();

        Integer num = n;
        String s = num.toString();

        if (n == Integer.parseInt(s)) {
            System.out.println("Good job");
        } else {
            System.out.println("Wrong answer.");
        }
    } catch (DoNotTerminate.ExitTrappedException e) {

        System.out.println("Unsuccessful Termination!!");
    }
